It has been found desirable to makethe cover for a laminated spring for a motor car in such manner that when said cover is in osition on the spring, there obtains at eacii end of said cover a closure on the spring which prevents the exudation of grease from said cover, and also the entry of dust into said cover. It has also been found desirable that there should be a (li-' rect and liquid-tight connection at the meeting edgesof the cover.

A further feature of the invention is to provide a novel Fastening means whereby the meeting edges of the cover may be readily drawn together and locked. \Vith these objects in view, the invention consists in the novel construction, combination and arrangement. of parts hereinafter described. illustrated and pointed out in the appended claim.

The invention is illustrated by the accompanying sheet of drawings, which shows the invention as applied to a lubricating cover for a laminated spring of a motor car.

Fig. 2 shows a. cover closed up as when in position on a spring, the cover being partly broken away.

t or interlocking loops'c and through In-earrying outthe invention, the cover a, of leather or other suitable material is provided in and at each end with a short adapted to, fit around the inside of. each end of said cover and over the spring ends, so that when the ends ofsaid cover have been fastened around said s ring ends, there obtains a perfect non-leak tight closure on the ends of the spring.

To draw and fastenthe meeting edges of the cover together, said meeting edges are provided with a series of interengaglng sax loops 0 is threaded, in the manner indicated in dotted lines" in Fig. 1, a thong-or the like. (Lwvhich cord (1.011 being pulled taut and. straight brings the looped edges into en- I tube 6, of leather or other suitable material,

ing and dust- 66 gagelnent with one another as shown in Fig. 2.

To prevent dust or liquid passing between the-edges of the loops 0 and penetrating to the interior of the; cover a, there is provided a longitudinally extending tongue (1 which is attached to the underside of one of the meeting edges of the cover, and to more securely fasten the cover a to the spring, buckles and straps f may be employed Having now described my invention, what I claim as new and desire to secure by Letters Patent of the United States is Flexible covers for laminated vehicle springs, including in combination, a leather cover, a leather tube located imand at each end of said cover, a series of interengaging loops on the meeting edges of said cover, a thong threaded through said loops, and a' tongue locatedinside and along one meeting edge of said cover.
